wispborne / ViewOnceData.kt

Last active October 3, 2018 08:14

A class that encapsulates data, adding ability to know when the data has already been viewed. Useful for putting one-shot events, like "display dialog", into a State object that can be reapplied to a view.

	import java.util.concurrent.atomic.AtomicBoolean

	/**
	* Wraps some data that should track when it has been viewed and allow future viewers to avoid a second showing.
	* Useful for showing messages in the app that auto-hide because this class can exist in the app's state.
	*/
	data class ViewOnceData<T>(private val data: T) {
	val wasViewed = AtomicBoolean(false)
